CC -!- FUNCTION: Involved in the biosynthesis of the arabinogalactan (AG)
CC region of the mycolylarabinogalactan-peptidoglycan (mAGP) complex, an
CC essential component of the mycobacterial cell wall. Catalyzes the
CC transfer of the first two galactofuranosyl (Galf) units from UDP-
CC galactofuranose (UDP-Galf) onto the rhamnosyl-GlcNAc-diphospho-
CC decaprenol (Rha-GlcNAc-PP-C50) acceptor, yielding galactofuranosyl-
CC galactofuranosyl-rhamnosyl-GlcNAc-diphospho-decaprenol (Galf-Galf-Rha-
CC GlcNAc-PP-C50). Thus, GlfT1 is the initiator of galactan synthesis,
CC while GlfT2 continues with the subsequent polymerization events.
CC {ECO:0000250|UniProtKB:P9WMX3}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-L-rhamnosyl-(1->3)-N-acetyl-alpha-D-glucosaminyl-
CC diphospho-trans,octa-cis-decaprenol + 2 UDP-alpha-D-galactofuranose =
CC beta-D-galactofuranosyl-(1->5)-beta-D-galactofuranosyl-(1->4)-alpha-
CC L-rhamnosyl-(1->3)-N-acetyl-alpha-D-glucosaminyl-diphospho-
CC trans,octa-cis-decaprenol + 2 H(+) + 2 UDP; Xref=Rhea:RHEA:34379,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:58223, ChEBI:CHEBI:66915,
CC ChEBI:CHEBI:67209, ChEBI:CHEBI:67210; EC=2.4.1.287;
CC Evidence={ECO:0000250|UniProtKB:P9WMX3};
CC -!- PATHWAY: Cell wall biogenesis; cell wall polysaccharide biosynthesis.
CC {ECO:0000250|UniProtKB:P9WMX3}.
CC -!- SUBUNIT: Is probably part of an AG biosynthetic complex.
CC {ECO:0000250|UniProtKB:P9WMX3}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P9WMX3}.
CC Secreted, cell wall {ECO:0000250|UniProtKB:P9WMX3}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 2 family. {ECO:0000305}.
